announced via advisory DSA 1666-1.

Several vulnerabilities have been discovered in the GNOME XML library.
The Common Vulnerabilities and Exposures project identifies the
following problems:

CVE-2008-4225

Drew Yao discovered that missing input sanitising in the
xmlBufferResize() function may lead to an infinite loop,
resulting in denial of service.

CVE-2008-4226

Drew Yao discovered that an integer overflow in the
xmlSAX2Characters() function may lead to denial of service or
the execution of arbitrary code.

For the stable distribution (etch), these problems have been fixed in
version 2.6.27.dfsg-6.

For the upcoming stable distribution (lenny) and the unstable
distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your libxml2 packages.
